When a photographer asked the Simple Life star, "When do yo think it will be your turn?", the smiling star ignored him and made her way inside.

Hilton and Kardashian's friendship ended many years ago; Hilton has since apologized for publicly mocking the Armenian star's butt in a radio interview. "It's 100 percent jealousy," a source told Us Weekly of Hilton in 2010. "Kim is not only doing what Paris did, she's doing it better."

Kardashian, meanwhile, recently told Us she's "feeling good" during her first trimester. "I haven't had any morning sickness, but it still isn't the easiest," she admitted. People always say it's easy and fun. It's definitely an adjustment learning about your body and stuff like that. I've been feeling really good, so that's good."

Though she doesn't have any baby news to report, Hilton is happier than ever -- and so is her man. "So much fun at the People's Choice Awards with my beautiful love, Paris," Viiperi tweeted. "I won have the hottest and best girlfriend, but they didn't have that category this year."
